I have always been old school using aluminum AR mags. I am now starting to like the polymer mags more each time I hand load them and shoot them. But, I like the Series 3 MAGPUL PMAGS. And, they are hard to come by at reasonable prices ($10.00 or less). But, I have come across some Troy and Hexmags for less than $11, which I can live with that price. Of course, all of these are 30 rd. mags. How do the Hexmags and Troy mags compare to the MAGPUL PMAGS?
Personally, I prefer Lancers, Troys, and MagPul Pmags, in that order. Nothing much wrong with any of these three in my opinion as far as polymer mags go. I might give the Lancers and Troys a slight edge, because they don't feel as bulky as the PMags. Really that is my only knock on the Pmags, other than that some generations tend to fit too tightly in some magwells. Of course, aluminum GI mags are usually good to go.
Price wise the Troy Mags and Pmags are hard to beat. You rarely see Lancers for less than $15 to $17 apiece. Although I have gotten some 30 round solid color lancers for about $10 each a couple years back.
I have a few Troy magazines and they have held up well and I would recommend them. People have their opinions about Troy's politics/hiring practices, etc., but the bottom line is that they do make good products. I run their sights on every AR that I have. The only downside I see with the Troy magazines is how their floor plates are held on.
My Troy Mags came with the option of flat floor plates or with pull tabs. They just happened to have the pull tabs installed and I removed them and replaced them with just the flat floor plates.
I could see the potential for problems with the Troy's floor plates if you are the anal type that likes to take stuff apart all the time, even when not really necessary for cleaning (like when a quick swipe with a wet or dry cloth would suffice), as the plastic tabs are soft and don't necessarily look like they would do well with repeated unnecessary disassembly. You know what I am talking about.... like the people who will completely disassemble a Glock pistol, not just field strip it for a normal cleaning, and then complain that the plastic push pins holding it together have worn out and loosened.
I have no experience with Hex mags so I will leave you to other peoples opinions on those.
